Abstract: A harvesting vehicle includes a header having a cutter bar, a crop transport draper and a reel mounted above the cutter bar to sweep the crop to the draper. The operation of the header is autonomously monitored and controlled to reduce operator loads or to run autonomously by detecting: reel wrapping; differential rates of flow of crop on the header at different locations; where the crop to be cut is at least partly lodged so that stems of the crop are not vertical; the presence of a crop streak of uncut or poorly cut crop behind the cutter bar and/or a band of disturbed soil behind the cutter bar. The detector is arranged to control ground speed, header height, reel height and operation.

Abstract: A three-dimensional stereoscopic image display system comprising an observer position guide configured to guide an observer wearing stereoscopic three-dimensional glasses to a position to perceive a three-dimensional image based on the position of the observer position guide.

Abstract: The present disclosure describes techniques for improving image quality when a camera-based barcode-reading device is reading barcodes located on objects that are moving relative to the barcode-reading device. The techniques disclosed herein enable the image sensor in the barcode-reading device's camera to remain aimed at an object that is moving relative to the barcode-reading device while the camera is capturing an image of the object. Advantageously, the techniques disclosed herein can reduce image blur. In a barcode-reading device that includes a rolling shutter-type image sensor, the techniques disclosed herein can also reduce image distortion.

Abstract: The patient interface may comprise an axis for alignment with an axis of the eye such as an optical axis of the eye. The interface may comprise a guide to allow the interface to move along the axis with the eye, which can inhibit increases in intraocular pressure when the patient is aligned with the laser. The interface may comprise a lock to hold the patient interface at a location along the axis, which can maintain alignment of the patient with the laser eye surgery system. The interface may comprise a plurality of transducers to measure forces to the eye during surgery. The laser eye surgery system can be configured in one or more of many ways to respond to the measured forces. For example, the system may offset the position of laser beam pulses to increase the accuracy of the placement of the beam pulses on the eye.

Abstract: A display assembly includes: a scene display screen; a privacy screen mounted over the scene display screen; a first mirror having a reflection side (“the first reflection side”) and a transmission side (“the first transmission side”). The first reflection side is mounted at an angle to the scene display screen for illumination; a background display screen faces the first transmission side for illumination thereof; and a housing arranged about the scene display screen, background display screen and first mirror for reducing ambient light within the housing including an opening for viewing of the reflection side of the first mirror therethrough. An image generation assembly is coupled to the scene display screen for producing a moving scene image thereon. The observer views the background display screen and the scene display screen simultaneously when viewing the reflection side of the first mirror and the privacy screen prevents viewing a secondary scene image.

Abstract: A needle hub (10) for a pen needle is provided with an enlarged surface for contact with the skin of a patient. The enlarged surface is provided with a surface having a dimension and shape to enable a needle or cannula to penetrate the skin to a desired depth and permit substantially the entire exposed length of the needle or cannula to penetrate the skin to the desired depth. The surface of the needle hub can be formed by an inner cone shaped member (26) forming a first contact surface with a surface area of about 1-5 mm2 and an outer ring (28) at a peripheral edge forming a second contact surface with a combined surface area of about 15 to 50 mm2.

The floor openings and the sidewall openings cooperate between the two coaxial components such that flow of gases through the floor and upright sidewall of the baffle structure is controlled by rotation of the two vertically coaxial components relative to one another.

Abstract: An autonomous mobile device (AMD) may perform tasks within a physical space. The AMD may move over ramps, bumps, or navigate around obstacles. The AMD may have an inertial measurement unit (IMU) and distance sensors. The IMU provides tilt information indicative of the AMD being on a flat surface or a ramp. The distance sensors provide information on distances between the AMD and surrounding obstacles. Using IMU measurements, the AMD determines a first speed limit that is safe given the tilt of the AMD. Using the distance sensors, the AMD determines a second speed limit that is safe given a distance to an obstacle. The AMD determines a maximum speed based on the first and second speed limits. Based on the maximum speed, the AMD determines whether to adjust a current speed and by how much.

The combustion chamber has an outer wall defining an outer chamber. The outer wall is perforated to admit combustion air from a pressurized air plenum to the inner wall. The inner and outer wall are spaced apart such that air may flow between the inner and outer walls.

Abstract: A reel of a harvester including a cutter bar includes a plurality of reel bats which are pivotal so as to vary the angle of the fingers about the bat axis as the reel rotates. The reel is used with a cutter bar which can change in height at one or more positions along its length to accommodate changes in ground height and contour. In order to maintain the fingers of the reel as close as possible to the cutter bar for best crop control, there is provided a sensor at each of one or more positions along the cutter bar responsive to the cutter bar height and an actuator which changes the diameter of the reel bats at the respective position.

Abstract: A header for a crop harvester includes side drapers having a front edge adjacent the cutter bar and carrying crop to a discharge end roller at a center feed draper. A support arrangement carries the rear end of the discharge end roller to define an operating position in which an axis of the discharge end roller is at an angle to an axis of the outer end roller of the side draper with the rear end of the discharge end roller at a height below a height of the rear end of the outer end roller. This provides a main portion of the belt that lies in a common plane defined by an intermediate guide member and the outer end roller and a smaller portion of the draper belt between the guide member and the rear end of the discharge end roller which is twisted downwardly from the common plane.

Abstract: A draper header for harvesting crops includes a header frame with a middle frame section pivotally coupled between a pair of side wing sections. A cutter bar assembly extends across a front portion of the header frame and is flexible with the side wing sections for cutting the crops to be harvested. A pair of crop pick-up reels are rotatably supported by center and outer reel support arms for engaging the crops to be harvested. A sensing system is operatively coupled to the header frame for detecting when at least one of the side wing sections pivots downwardly relative to the middle frame section. When the sensing system detects that at least one of the side wing sections pivots downwardly past a predetermined pivot angle, a down-stop cylinder is actuated to raise the crop pick-up reels, thereby preventing contact of the crop pick-up reels with the cutter bar assembly.

Abstract: An autonomous mobile device (AMD) may move around a physical space performing various tasks. Most of the sensors on the AMD may be directed towards the front and sides of the AMD to facilitate autonomous navigation, interactions with users, and so forth. The AMD may return to a dock to recharge batteries, replenish consumables, transfer payload, and so forth. The AMD uses the sensors to approach the vicinity of the dock. Once in the vicinity, the AMD turns around and backs into the dock. This orientation allows the AMD to continue to operate the forward-facing sensors and interact with users while docked. The AMD uses inductive sensors to detect metallic targets located at particular positions in the dock. Output from the inductive sensors provides information about the relative position of the AMD with respect to the dock and is used to steer the AMD into a desired docked position.
